Try a used Dell Precision series from the past 6 years. That should be roughly in that price point and will probably be an old business cast off with either decent integrated graphics or a real graphics card depending on how patient you are about waiting for a good deal. They are solidly made with aluminum cases and made to take a beating. I have a Precision I bought used from 2012 that's still going, and just got another from 2020 for about $230 usd with shipping. Mind you this is a US perspective and I don't know much about international markets.
